I would be interested to see this also, it is literally the only reason I am considering BM3, I don't want more power just the bloody lag fixed lol

Someone might capture some logs and then you could compare with the logs in the long thread I started about this long ago. To be honest, the issue is so fixed, you should just trust everyone’s comments and go get the tune. As far as I’m aware, I was the first on this forum to bring up the issue and document it ad nausea. I also tried everything I could to fix it, and reported on that failing too. I’d hope that would give me credibility you can trust when I say it is now fixed.... I’m also British and therefore a gentleman and wouldn’t lie ;-)

Anyone notice that the comfort & sport throttle mappings on these OTS V5.9 tunes is different to stock (at least iStep F020-18-11-531 from December 2018)?
The throttle differences when switching between Comfort/Sport/Sport+ remind me of my car with the original July 17 LCI iStep, at steady low throttle positions there are very noticeable increases with each change from Comfort to Sport to Sport+. I remember noticing a change when my iStep was updated December 18, at the same steady low throttle positions there is barely a change going from Comfort to Sport (no change up to I think 20% pedal position) but then a dramatic change going Sport to Sport+. I've just done short drives on v5.9 Stage 2 91 & 93 & my stock tunes. With v5.9 Comfort feels just slightly more sluggish than stock while Sport is definitely more sensitive than the stock Sport. I didn't have an opportunity to really test the 6MT load drop fix but that lag hasn't been an issue for me shifting fast with the Auto Solutions SSK. Before the SSK or if I shift fractionally slower the lag was/is there. I've gone to an OTS tune temporarily as it seems there are issues with my Jordan custom tune, have to say though the custom throttle feature (I had Sport in place of deleted Sport+) makes Sport+/MDM much more useable. |

I've been on 5.7 Stage 2 91 ACN probably since about when it was released and just logged on and saw that there's an update. Googled WTF the "6MT gearshift load drop fix" was and found this thread. Super stoked to try it.
But it looks to me like upgraded intercooler is now required. Before it was "recommended." I know everyone felt it was required anyway, but I don't track it and really only reserve the full pedal for the occasional glory run, never when it's 110F, etc., and haven't experienced any issues. So the $24,000 (replacement engine cost) question is: is there any functional difference impacting IAT that would truly be different between 5.7 and 5.9? Thanks for any educated or informed responses. |

Stage 2 is more fun! I'm just trying to get an idea if it's now more risky IAT-wise than it was before with 5.7.
I never really messed around much with Stage 1, and my recollection from threads back in the day was that the N55-based M2 was pretty dialed from the factory and Stage 1 didn't do much. Agree that it would be worth the price of admission for the lag fix regardless, but of course I want it alllllll I'll do the update to the 5.9 map and probably stay on Stage 2 but be even more cautious until I get confidence I'm not endangering my mill. |

Wow, like it would revert to a less aggressive tune at high IAT? I've just been quietly minding my own beeswax for the last year or 2, but it really seems like BM3 has been upping their game.

stock tune pulls power when IAT is past a threshold. OTS tunes keep this safety 'feature', however the changelog imply that the tables were revised.

i just looked into the n55 ewg (non M2) stock tune and looks like when IAT is above 75C, then load is reduced.
fun fact: i then overlaid the m2 map over it to see the difference.. and it seems the m2 map does not limit the load per IAT??

75C/167F is hot! The map should just turn your car off and not let you drive if it gets that high! |

I was waiting for the warranty to expire next year to modify the powertrain, but those temps, and the noticeable drop in power convinced me to upgrade the IC. |

The highest IAT I’ve seen on a 100F track day was ~160F. That was with my Dinan Stage 4 setup (Dinan turbo, Dinantronics, Dinan IC) and stock downpipe. So far the highest IAT I’ve seen on a 100F day with Stg 2+ E30, 300-cell DP, and the Wagner Evo3 is ~135F, but I need to get some more logs. Last edited by ZM2; 07-01-2021 at 11:53 AM.. |

if you have an m2, then go into map editor and open the same table and let us know what the stock m2 map does for IAT compensation.

This isn't necessarily related to this specific update, but I would really like to see some changes to initial throttle on Sport+.
At least on my DCT car, I essentially cannot drive off from a cold start in Sport+ with out a very strong jerking. Essentially, on very light throttle (just moving around a parking lots speeds/acceleration) the car will surge up and down in power so that a smooth takeoff at low speeds is nearly impossible. Does anyone else experience this, or is it just an idiosyncrasy of my car? |
